Heat recovery system, meaning ventilation without heat loss

Do you want to always have fresh, clean air without worrying about a significant decrease of the temperature? Do you often open windows to oxygenate the body and get rid of the unpleasant smell of not ventilated air, letting in the pollutants from outside? I’ll say! You are actually letting CO2 out of the room which is harmful to health, damned if you do and damned if you don’t. Heat recovery system, which is mechanical ventilation with heat recovery, will resolve all your problems! Guaranteeing you not only a clearly perceptible increase in everyday comfort, but also saving on heating costs!

Unlike traditional ‘gravity ventilation’, recuperation does not need to unseal the windows in the building or install special vents in them, nor does it need low outside temperatures in order to work effectively. “Gravity ventilation” works on the basis of the difference between the temperature outside and that inside the house, meaning it works when you don’t want it to, because it’s cold outside and warm inside, or in the summer when it’s too warm inside and too cold outside. Otherwise gravity ventilation is just there and doesn’t work how it should be working. Heat recovery system, which is mechanical ventilation with heat recovery, allows constant flow of used and fresh air enabling heat recovery between them. That’s why air coming into the house have temperature similar to the one in the room.

Heat recovery system is made out of two elements. First one is a recuperator, which is a special device being a head office of mechanical ventilation enabling an exchange of heat energy between two streams of air – from inside a building and the one ventilated from outside. The second element are air transport canals responsible for it’s supply and discharge from and into the recuperator, including plenum boxes, air distribution boxes and adequate insulation.

We also highlight decentralized heat recovery system, which consists only of a not so big recuperator shaped in the shape of a circle, which we put through the wall, and it alternately pulls out warm air and blows in warmer air than outside. This device gained popularity in last years due to already finished buildings and flats, with emphasis on the last one, because let him be the first to cast a stone who has been in a well-ventilated tenement or block of flat without mechanical ventilation.
